WINDOW Filed Jan. 10, 1939 2 Sheets-Shet 2 elis A tiorneys Patented Jan. 21, 1941 UNITED STATES PATENT OFFICE 1 Claim.

This invention relates to a window structure which includes a frame and upper and lower sashes, the general object of the invention being to provide means whereby the sashes are slidably arranged in the frame and also pivotally arranged so that the sashes can be swung inwardly to a horizontal position or to any position between the vertical and the horizontal, whereby I the transparent members of the sashes can be easily cleaned and any repairs may be made to the sashes without necessitating one operating from the exterior of the building and without removing a screen covering the exterior of the frame.

A further object of the invention is to make the structure practically air-proof when the sashes are closed.

A further object is to so construct and arrange the parts that they can be manufactured to sell at low cost as the product entails the minimum amount of labor and material, as the parts are so constructed and arranged that there is little danger of the parts Wearing or getting out of order, and the upkeep is reduced to a minimum.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claim.

In describing the invention in detail reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is an elevation looking toward the interior parts of a window structure constructed in accordance with the invention.

Figure 2 is a section on line 2-2 of Figure 1 40' with most of the parts in plan.

Figure 3 is a section on line 3-3 of Figure 1.

Figure 4 is a fragmentary perspective view of the upper sash.

Figure 5 is a fragmentary vertical sectional view through a portion of a sash and portions of the frame and showing the sliding clip or plate to which the sash is pivoted and also with which the chain is connected.

Figure 6 is a fragmentary one side plate of the frame.

Figure '7 is a perspective view of an upper corner of the lower sash and showing the latch means.

In these drawings the letter A indicates the window frame which is provided with the usual perspective view of stool a at its lower end and this frame may be formed of wood, as shown in the drawings, or metal. If the frame is formed of wood metal plates l are fastened in any suitable manner to the inner faces of the side members of the frame and a pair of channel-shaped guide members are welded or otherwise attached to each plate I. However, if the frame is of metal these guide members are welded directly to the frame members. As shown these guide members 2 are vertically arranged and are spaced apart and the outer ones form guides for the upper sash B and the inner ones form guides for the lower sash B. Each member 2 has its flanges bent outwardly as shown at 2 and each sash has a plate 3 attached to each side edge thereof, the. front edge of each plate being bent to form a small channel 4 for receiving a front flange 2'. However channel 4 terminates in spaced relation to the lower edge of each sash, as shown more particularly in Figure 4, and a channel-shaped clip or plate 5, having its flanges bent inwardly, as shown, is pivoted to the lower end of each plate 3 as shown at 6, the inner flange of this plate or clip forming a continuation of the channel 4 when the sash is in vertical position. The flanges of these plates 5 fit over the flanges of the guide members 2 and in order to permit these plates 5 to be placed in engagement with the members 2, each plate I terminates a short distance above the lower end of the frame and a short plate I fills the space between the lower end of the plate I and the bottom of the frame and this plate I carries the guides 2" which form continuations of the guides 2. Thus by removing these short plates I the clips or plates 5 can be placed in engagement with the guiding members or removed therefrom when it is desired to entirely remove the sashes from the frame. A spring strip 1 is fastened to each clip 5, preferably by the pivot 6 and a strip 8 of felt or the like is carried by the strip 1, these parts being rolled as shown in Figure 5 and form a wiper for operating in the guides 2 as the sash is raised or lowered and they prevent passage of air through the guides 2 and thus prevent any air from entering the guides and passing into the room. The weight chains 9 have the lower ends connected with the pivot bolts 6 and these chains pass through the channels formed by the guides 2 and said chains pass through the slots H] formed in the webs of the guides and through similar slots in the side members of the window frame and over the pulleys ll carried by said side members and said chains are connected with the Weights I2.

Latch members I 3 are pivoted to the upper corners of the lower sash and are normally held in engagement with the outer flanges 2 of the inner guiding members 2 by springs I 4. A latch member I5 is pivoted to an upper corner of the upper sash and engages an elongated vertically extending strip I6 located between the guiding members 2 at one side of the window. While the drawings show but one of these latch members I5 engaging a strip I6 it will be understood that if desired two of these latch members I5 can be carried by the upper sash and each plate I provided with a strip I6 for engagement by these latches I 5.

As it will be seen, when the sashes are in vertical position the channels 4 will be engaging the inner flanges of the guiding members 2 and the latches I3 of the lower sashwill be engaging the outer flanges of the inner guiding members 2 while the latch member I5 will be engaging the strip" I6. Thus the two sashes are prevented from swinging inwardly and they can be moved in vertical position on the guiding members. When it is desired to swing either sash inwardly the latch means of said sash are moved to released position and then the sash can swing inwardly on the pivots 6. When the sashes are in vertical position the engagement of the channels 4 with the bent flanges of the guiding members 2 will form weather strips to prevent leakage of air between the sashes and the frame and, as

I before stated, the members I and 8 operating in the channels of the members 2 will prevent air from flowing through said channels into the room. Also interlocking weather strips [1 are carried by the lower member of the upper sash and the upper member of the lower sash as shown in Figure 3 and to prevent the passage of air through the space between the members 2 at the ends of these weather strips I'I blocks I8 are fastened to the side members of the frame between the membersZ and at the point where the strips I1 interlock when the two sashes are closed. In other words these blocks form continuations of the strips I'I between the members 2. Also projections I9 extend outwardly from the upper corners of the lower sash to fit between the blocks and the ends of the weather strips I! when the sashes are closed to still further reduce the danger of air passing into the room at these points.

The bottom of the lower sash is formed with a groove 20 for receiving a bead on a weather strip 2I fastened to the upper face of the bottom member of the frame, when the sash is closed, and a similar groove 22 is formed in the upper end of the upper sash to receive the bead of a Weather strip 23 attached to the under face of the top member of the frame when the upper sash is closed.

A length of chain 24 is fastened to each upper corner of the lower sash for engaging hooks 25' carried by the side members of the frame for holding the lower sash in inclined positions, as shown in dotted line in Figure 3. However, when the lower sash is in lowered position it may be tilted inwardly a slight distance and it will remain in this position without the use of the chains 24, due to the fact that a part of the lower edge of the sash will engage the bead of the strip 2I and another portion of the sash will engage a portion of the stool a. Also as shown in Figure 3 in dotted line, both sashes can be swung to a horizontal position when desired.

The sashes may be locked in closed position by the usual locking means 26.

A screen-carrying frame 21 is placed in the frame at the outer portion thereof and removably held in place in any suitable manner and.

it will be seen that the sashes can be swung inwardly for cleaning and repair purposes without removing the screens and Without necessitating the workmen Working on the parts exteriorly of the building. Also by having the sashes arranged in the frame as specified and shown the building can be ventilated by holding a sash in tilted position and without danger of rain, snow or the like entering the building, and also without creating a draught in the building.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts provided that such change falls Within the scope of the appended claim.

Having described the invention what is claimed as new is:

A window structure of the class described comprising a window frame, channel-shaped guide members connected with side faces of the frame, upper and lower sashes, small plates pivotally connected with the lower ends of the side edges of the sashes, each small plate being of channel shape in cross section and having its flanges bent to slidingly engage the flanges of a guide member, each pivot extending into the space formed by the flanges of the small plate, weight carrying flexible members passing downwardly through the guide members and having their lower ends connected with the pivots of said small plates and latch members at the upper portions of the sashes for holding the sashes in vertical position and wiper means located in the spaces formed by the flanges of the small plates and attached thereto by the pivots, said latch means for the upper sesh including a latch member pivoted to the inner face of an upper portion of said upper sash, and a vertically arranged strip attached to a side member of the window frame and located between the guide members and engaged by the latch member.
